We divide 71812491 by 805
We want to figure out the number of times 71812491 can be divided by 805.

Step 1:
805 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 805

On to step 2:
When dividing 71 by 805, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 805

Advancing to step 3:
The number 805 fits into 718 0 times, leaving a remainder of 718.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 718, we get 718.
Bring next digit (1) of the dividend behind the 718 and repeat the process: 7181 / 805

On to step 4:
If we divide 7181 by 805, we get 8 and a remainder of 741.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6440 from 7181, we get 741.
Bring next digit (2) of the dividend behind the 741 and repeat the process: 7412 / 805

Let's proceed to step 5:
The number 805 fits into 7412 9 times, leaving a remainder of 167.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 7245 away from 7412, we end up with 167.
Append the next digit (4) from the dividend to 167 and continue with: 1674 / 805

Moving on to step 6:
1674 divided by 805 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 892.0
Deduct 1610 from 1674 and we're left with 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 805

Step 7:
If we divide 649 by 805, we get 0 and a remainder of 649.
The number 0 becomes the next digit in our result. 
Result so far: 8920.0
Deduct 0 from 649 and we're left with 649.
Take the next digit (1) from the dividend and append it to 649, then repeat: 6491 / 805

Let's proceed to step 8:
805 can be fit into 6491 8 times, resulting in a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 89208.0
Subtracting 6440 from 6491 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
When dividing 510 by 805, we get 0 with a remainder of 510.
The next digit of our result is 0. 
Result so far: 89208.0
The remainder is 510 after subtracting 0 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 10:
If we divide 5100 by 805, we get 6 and a remainder of 270.
Use 6 as the next digit of our solution. 
Result so far: 89208.06
Deduct 4830 from 5100 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 11:
If we divide 2700 by 805, we get 3 and a remainder of 285.
Put 3 as the next digit of the answer. 
Result so far: 89208.063
Subtract 2415 from 2700 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 12:
805 goes into 2850 3 times with a remainder of 435.
Record the quotient 3 as the next digit in the result. 
Result so far: 89208.0633
Deduct 2415 from 2850 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

The final outcome is 89208.0633, with a leftover of 0.00435.
